Specification of Letters Patent Patented Oct. 13, 1914.

Application filed Became-@1912. Seria1N0.736,601.

To all whom it may concern Be it known that I, I'IARRY U. Eiiernn, of!

and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this speciiication, and to thereference-numerals marked thereon.

My present invention relates to lanterns and it has for its object toprovide a simple, cheap and convenient means for mounting the bell ofthe lantern and for operating the same in an eilicient manner toward andfrom the globe to maintain the latter securely in place on its supportor release it therefrom. I

To these and other ends the invention consists in certain improvementsand com binations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a front elevation of a lantern constructedin accordance with and illustrating one embodiment of my invention; Fig.2 is a side elevation thereof, partly in section, showing the bellraised to release the globe; Fig. 3 is a per spective view of theoperating member for the bell and the part on which it is directlymounted, and Fig. 4: is a perspective view of the operating memberalone.

Similar reference numerals throughout the several figures indicate thesame parts.

I have illustrated my invention, in the present instance, as embodied ina tubular lantern of a familiar type comprising, in general, an oil font1, burner 2, air chamber 3 and side tubes 4 communicating with the airchamber and in which the bail 5 is journaled. A plate 6 surrounding theburner supports the globe 7 with the assistance of clips 8.

At their upper ends, the tubes 4 lead from a center tube 9 constitutingpart of a dome indicated generally by 10 and which also comprises a cap11 and a central inner chimney 12. The latter is provided at its lowerend with the usual flange 13 to prevent down draft and is supported by aflange 14: at its upper end that seals the upper end of the tube 9 justbeneath the cap 11. A short tube 15 having a perforated flange 16suitably whole.

secured to the lower end of the tube 9 constitutes an inner collar onthe latter that is spaced from the cyllndrical walls of the tube 9though rigid therewith and within this collar slides the uppercylindrical portion 17 of a bell 18 that is guided between the collarand the chimney 12 for vertical move.- ment, to which end its upperextremity is turned inwardly at 18 to provide a bearing against thechimney tube.

The bell 18 performs the usual function, being provided with a flaredand beaded portion 19 whereby it may make a tight joint with theshouldered upper rim 20 of the globe 7, and it may be further guided byclips or shoes .21 attached at this point and running on ribs 22 on thetubes 4.

The means I prefer to employ for eifecting the up and down movement ofthe bell between the operative position of Fig. 1 and the inoperativeposition of Fig. 2 in which the globe 7 is released for removal orlighting purposes, comprises a rotary ring 23 that encircles and slidesuponthe collar 15 within the tube portion 9 of the dome 10, beingconfined between the flanged portion 16 thereof and lugs or othersuitable devices 24 engaging it from above. The ring may be convenientlyformed of a length of wire,

one extremity of which is passed through.

one of the segmental perforations 25 of the flange 16 and fashioned intoa loop 26 that constitutes a finger-piece, from which loop proceeds aprojection 27 that lies beneath the flange 16 and clear of the dome as aThe said projection 27 cooperates with the double cam surfacesconstituted by the opposite walls of a slot 28 extending peripherally ofthe upper cylindrical portion 17 of the bell 18 at an inclination to itsaxis.

The operation of the device will be readily understood.

If the parts are in the position of Fig. 1, audit is desired to raisethe dome, the operating ring 28 is rotated to the left by means of theloop or finger-piece 26 whereupon the projection 27 riding in engagementwith the upper cam surface of the slot 28 will raise the bell on itsguide to the position of Fig. 2, whereas the reverse movement will lowerthe parts, and it is to be noted that in the normal or operativeposition of the bell, as shown in Fig. 1, the operating member 26 liesclose against one of the tubes 4 and out of the way. Short shoulders orhorizontal portions 29 may be formed at the ends of the slots 28 to lockthe projection 27 in a neutral position, while the bell is in either itsraised or lowered position.

It will be noted that the open ring 28 is so disposed on the collar 15that when it is moved to the left to raise the bell18, which operationimposes more strain on the operating member than does the loweringthereof, due principally to the convergence of the guides or ribs 22,the said ring is rotated in that direction which imparts a tendency forit to contract instead of to open and for the looped end carrying theprojection 27 that directly receives the strain to hug the collar 15closely for support so that disengagement is prevented. The reversemovement causes a tendency for it to pull away but with the lowering ofthe bell the strain is not great and besides a lug or oil'- set loop 30may be provided which travels on the opposite side of the slot 25, asshown, to-guard against the wire slipping into the slot. By making thering an open one, it may be readily attached to or detached from itssupport. To detach it, the operating portion is moved to the extremeright in Fig. 3, and then the adjacent circular portion forced out fromthe collar 15 as it is slowly returned to the left end of the slot whileat the same time the portion of the flange 16 on the outside of the slotis sprung to permit the loop 30 to pass inwardly beneath the lower edgeof the collar. The rest of the ring then readily follows through. Toapply the ring, a reverse operation is resorted to.

I claim as my invention:

1. In a lantern, the combination with a globesupport and a dome abovethe same, of a bell slidably mounted directly on the dome and movablevertically relatively to the dome and a rotary operating member for thebell movable about the dome as a center in dependently of the connectionof the dome and bell.

In a lantern, the combination with a globe support and a dome above thesame, of a bell slidably mounted directly on the bell and movablevertically relatively to the dome, a rotary operating member for thebell movable about the dome as a center and connections between the belland its operating member comprising a cam surface on one part and aportion on the other cooperating therewith.

o. In a lantern, the combination with a globe support and a dome abovethe same, of a bell slidably mounted directly on the bell and movablevertically relatively to the dome, a rotary operating member for thebell movable about the dome as a center and connections between the belland its operating member comprising coextensive cam surfaces on the bellextending peripherally therei'if at an inclination to its axis and a)rejection on the operating member engagng between the surfaces wherebythe bell nay be moved positively in either direction.

In a lantern. the combination with a globe support and a dome above thesame,
